COMPENSATION-TYPE ACCELEROMETER Russian patent published in 2015 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: compensation-type accelerometer is intended for use in the stabilisation and navigation systems. The device comprises a sensing element, position sensor, the output of which is connected to the amplifier input with a stable amplification factor, magnetoelectric power converter connected to the negative feed-back. Meanwhile it is additionally added by analogue, integrating and discrete integrating negative feed-backs. The analogue negative feed-back is made from the position sensor output to one of inputs of the magnetoelectric power converter through series connected to information inputs the AC amplifier, first logic element, XOR element, filter, first voltage - current converter and summator. The integrating negative feed-back is made from XOR element output to the magnetoelectric power converter input through series connected to information inputs the first integrator, second voltage - current converter and the summator. The discrete integrating negative feed-back is made from the XOR element output to the magnetoelectric power converter input through series connected to information inputs the second integrator, trigger and summator. Besides, the reference voltage generator is connected both to the position sensor, and to the phase shifter, the output of which is connected to one of the XOR element inputs through the second logic element, and one of the trigger outputs is connected to the input of a backward-forward binary counter, the output of which is a discrete output of the compensation-type accelerometer.

EFFECT: expansion of passband and improvement of accuracy of acceleration measurement.
